Document Type and Number:
WIPO Patent Application WO/2022/065640
Kind Code:
A1
Abstract:
The present invention relates to a thermoplastic resin composition, a preparation method therefor, and a molded product manufactured therefrom and, more specifically, a thermoplastic resin composition, a preparation method therefor, and a molded product manufactured therefrom, the thermoplastic resin composition comprising, relative to 100 parts by weight of a base resin containing: (A) 10 to 50 wt% of a vinyl cyanide compound-conjugated diene compound-aromatic vinyl compound graft copolymer; (B) 10 to 55 wt% of a vinyl cyanide compound-conjugated diene compound-aromatic vinyl compound copolymer; (C) 4 to 11 wt% of an acrylate-aromatic vinyl compound-vinyl cyanide compound graft copolymer having a grafting ratio of 40 to 60% and a weight average molecular weight of 150,000 to 200,000 g/mol; (D) 3.5 to 9 wt% of a vinyl cyanide compound-aromatic vinyl compound copolymer having a weight average molecular weight of 1,000,000 to 2,500,000 g/mol; and (E) 1 to 20 wt% of a branched vinyl cyanide compound-aromatic vinyl compound copolymer having a weight average molecular weight of 300,000 to 800,000 g/mol, (F) 0.1 to 2.5 parts by weight of a high-density polyethylene resin having a density of 0.9 to 1.5 g/cm3 and a weight average molecular weight of 1,000 to 6,500 g/mol. According to the present invention, there is an effect of providing a thermoplastic resin composition having excellent blow moldability and a wide molding temperature range, a preparation method therefor, and a molded product manufactured therefrom.
